Beer And Your Microbiome: Exploring The Connection

Beer is one of the most widely consumed drinks in the world, with a history of several millennia. It is rich in essential amino acids, vitamins, trace elements, and bioactive substances. The polyphenols in the malt and hops of beer are also important active compounds that interact with the gut microbiome.

Research has shown that drinking beer can help someone's gut microbiome become more diverse. This is true for both alcoholic and nonalcoholic beer. Both types of beer increase the diversity of the microbial populations in the participants' guts. There is also an increase in the activity of an enzyme, known as alkaline phosphatase, that helps defend the gut from bad bacteria.

The positive response is attributed to organic compounds known as polyphenols, which have been shown to possess antioxidant and anti-inflammatory properties and have been linked to a range of beneficial health effects. Beer also contains microorganisms that can contribute to the diversity of a beer drinker's gut microbiome.

Beer can increase gut microbial diversity

Based on the blood and stool samples that were collected at both the start and the conclusion of the study, researchers found that both types of beer increased the diversity of the microbial populations in the participants' guts. There was also an increase in the activity of an enzyme, known as alkaline phosphatase, that helps defend the gut from bad bacteria. Activity by this enzyme also indicates that the intestinal barrier, which allows for optimal immune function and nutrient intake, is working well.

Since both the alcoholic and nonalcoholic beers led to an increase in microbial diversity, researchers discounted alcohol as a contributing factor. Instead, they attributed the positive response to organic compounds known as polyphenols. Polyphenols have been shown to possess antioxidant and anti-inflammatory properties and have been linked to a range of beneficial health effects. Because beer is made via the process of fermentation, it contains microorganisms. These can also contribute to the diversity of a beer drinker's gut microbiome.

Beer can improve intestinal barrier function

Polyphenols, for example, can increase the biodiversity of the microbiota, stimulate the multiplication of bacteria that produce propionate and butyrate in the colon, and increase the production of short-chain fatty acids (SCFAs), which have local anti-inflammatory effects.

Beer also contains dietary fibre, such as non-starchy, non-digestible carbohydrates, which can serve as a nutrient substrate for the bacteria of the intestinal microbiota.

The melanoidins in beer, which are formed in Maillard-type reactions, also have prebiotic properties and can be fermented by the intestinal microbiota.

The combined actions of pre and probiotic factors can stimulate the proliferation or shift of the bacteria population towards a glycolytic one, normalising its profile.

Beer can positively impact the gut-brain axis

Beer has been shown to have antioxidant and anti-aging effects, promote estrogen production, reduce radiation damage, and help prevent cardiovascular events. It has also been shown to have a regulatory effect on various physiological functions of the human body. Moderate consumption of beer helps in preventing arteriosclerosis and heart disease, inhibits cancer, and improves blood circulation and immune function.

Beer contains many minerals such as calcium, magnesium, zinc, copper, selenium, and iron. Beta-glucan and arabinose-oligosaccharides stored in malting barley also make beer a source of dietary fiber. In addition, the polyphenols in the malt and hops of beer are essential active compounds with antioxidant activity that act synergistically with dietary components. The amino acids, vitamins, inorganic salts, and low molecular sugars in beer are quickly digested and absorbed in the small intestine. Polyphenols that are not hydrolyzed by the small intestine reach the colon and are metabolized by the body's microbiota.

The gut microbiome has long played an important role in human health. It is an essential medium for the body's intake of nutrients, and it is involved in the absorption and metabolism of nutrients, strengthens the integrity of the gut, prevents the spread of pathogens, promotes immune tolerance to antigens, and regulates host immunity, thereby directly influencing human health and disease.

The gut microbiome uses diet as a bridge to form a complex and dynamic mutually beneficial symbiosis with the host. At the same time, the intestinal mucosa and its vast micro-ecosystem together form a complex and dynamic immune barrier that participates in disease prevention and regulation of immune function through the interaction of microorganisms with the immune system.

Studies have shown that moderate beer consumption can reduce the expression of inflammasome signaling pathways in human macrophages. In such studies, the normal beer groups had significantly reduced intracellular protein levels of pro-IL-1β in primed macrophages, and the release of cleaved IL-1β protein was blocked. Transcription of pro-inflammatory interleukins such as IL-1β and TNF-α was also significantly reduced in the non-alcoholic beer group. That is, non-alcoholic beer may also enhance the immune response, leading to a more effective defense.

The polyphenols in beer have prebiotic properties. Studies have shown that phenolic substrates and the resulting aromatic metabolites supplied to intestinal bacteria through dietary intake may in turn cause fluctuations in microbial community composition through selective prebiotic effects and modulation of antimicrobial activity against enteropathogenic bacteria.

Beer can reduce the risk of chronic and metabolic diseases

Beer, the oldest alcoholic beverage in human history, is rich in essential amino acids, vitamins, trace elements, and bioactive substances that regulate human physiological functions. Beer has been shown to have a regulatory effect on various physiological functions of the human body.

The polyphenols in the malt and hops of beer are important active compounds that interact with the gut microbiome. These polyphenols have been shown to possess antioxidant and anti-inflammatory properties and have been linked to a range of beneficial health effects.

Beer also contains many minerals such as calcium, magnesium, zinc, copper, selenium, and iron. Beta-glucan and arabinose-oligosaccharides stored in malting barley also make beer a source of dietary fiber.

Research has shown that moderate beer consumption can reduce the risk of developing a wide range of chronic and metabolic diseases. This is due to the positive effects of bioactive substances in beer, which can help in the prevention of cancer, reduction of cardiovascular events, and modulation of metabolic syndrome.

The intestinal mucosa and its vast micro-ecosystem together form a complex and dynamic immune barrier that participates in disease prevention and regulation of immune function through the interaction of microorganisms with the immune system.

Most of the water, vitamins, and other low molecular weight substances in beer are absorbed in the stomach and small intestine. Polyphenols and other important substances reach the colon, where they meet the intestinal microbiota and are eventually transformed. Their metabolites inhibit pathogenic bacteria, stimulate the proliferation and activity of healthy flora such as Lactobacilli and Bifidobacteria, and regulate the intestinal microbiota.

In conclusion, beer can reduce the risk of chronic and metabolic diseases. This is due to the positive effects of its bioactive substances, which can help in the prevention of cancer, reduction of cardiovascular events, and modulation of metabolic syndrome. The gut microbiome plays a crucial role in this process by interacting with the bioactive substances in beer and regulating immune function.
